Front panel audio header cable adapter/extender?

[frau kaleun]

Motherboard: Asus M3A78-EM
Card: Asus Xonar DX

The audio FP header cable is as you described - one connector marked HD, the other AC'97. The original connection had the the HD connector plugged into the motherboard and the AC'97 connector free (which is how it is now). The card has an "optional" FP pinout that the documentation said you could connect up to the FP cable in order to use the FP headphone and mic jacks after installing the card and disabling the onboard audio.

When I first put in the card I just tried moving the HD connector from the board to the card but IIRC when I did that I got no sound at all, so I moved the HD connector back to the board and assumed that the FP pinout on the card was for the second connector on the cable and I would have to connect both of them if I wanted to use the FP jacks in conjunction with the sound card. Since I couldn't do that with the cable I had, I just plugged the HD connector back into the motherboard and left the card's FP pinout unconnected. I get fine sound from the speakers plugged directly into the card, but the FP jacks are useless.

This system is the first one I've had where I added a sound card that didn't come with it, so I'm learning all this stuff as I go - as per usual, since I can't resist the temptation to tinker - and maybe I'm completely misunderstanding how things *should* be hooked up, lol. I assumed that since there was also an FP pinout on the card, it meant I could use both connectors and run the cable to the card and the board whereas it could be I only have a choice of one or the other.

Anyway - if there is a way this should/could be hooked up that will give me the use of the front jacks, I'm all ears. But it's no biggie now, since I added newer speakers yesterday and found that there's a headphone jack on the control thingie which will be kept somewhere handy anyway, so as it turns out I do have a more convenient working option for headphone use. It's just that the "tinker gene" makes it almost impossible not to drive yourself crazy trying to make something work even after you don't absolutely need it work any more... just knowing that there's a feature that *might* work if I knew how to hook it up right is enough to keep me up nights, ya know?

I had a similar problem, I have a sound card now, but you have to go to control panel\Sound and Audio Devices\Audio and select the playback to the sound card rather than the motherboard, you can still leave the Sound Recording set to motherboard for input, I have the FP HD Audio plug on the X-fi Xtreme Creative sound card and use the motherboard AC97 mic and Aux inputs on the rear of the motherboard, works well.

Absolutely.

Can't tell how often I've taken something perfectly functional apart for no aparent reason, other than "I might be able to make this work a little better".


I have a similar hookup as Reece: FP connector goes to my X-fi (HD audio connector), but I use my onboard for my headset (connected at rear panel). My FP cable isn't shielded, so I get static noise when I connect anything to FP. Makes it pretty much useless.

My sound comes through the speakers through the card, while Skype is set to use the onboard. When I want to game with my headset, I change the default device in Windows to the onboard, and then everything comes in over the headset. A program can usually only use 1 audio device; key is to make sure the options are set correctly.


Gonna see if I can find the manual for that board and card,; maybe it's a special case. Let you know if I find anything.

Yeah, I'd just plug in the HD audio connector on the card, that should do it.

If you really want/need 2 seperate devices, you can leave the onboard enabled (if not, disable it in BIOS). Might get a conflict though; having both my card and onboard enabled caused a few BSODs with early Win7 beta.


Btw, some good documentation and nice software, especially for the soundcard. I didn't even know they made soundcards that require additional power though; mine just takes what it needs from the socket.

Copied from the manual. The first point seems critical:

• If you want to connect a high-definition front panel audio module to this connector, ensure that the front panel select item in the BIOS is set to [HD Audio]; if you want to connect an AC'97 front panel audio module to this connector; set the item to [AC97]. See page 2-27 for details.
• Make sure the audio device of Sound playback is Realtek High Definition Audio (the name may be different based on the OS). Go to Start > Control Panel > Sounds and Audio Devices > Sound Playback to configure the setting.

I think the first point just means you need to set which connector you used in the BIOS for proper functionality.

The second point is what was said about configuring a program or OS to use the proper device. It shouldn't be too difficult with just the card in there, but you'd definetly need to double-check if you have several devices (card+onboard for example, but even a single card can present multiple devices to the OS).

Whew, hope it helps.

Well, I currently have the HD connector from the FP plugged into the card - it doesn't make any difference that I can tell. The FP 'phone jack doesn't work no matter where I put the connector. I'm wondering if the fact that the speakers have a built-in 'phone jack on the control is disabling all other possible headphone jacks.

Is what you quoted from the card manual, or the motherboard manual? I have the card manual on hand but I hadn't saved or printed out the board manual yet and for some reason the Asus website doesn't want to load right now. I was there a few hours ago with no problems so I don't know what's up with that.

The card manual says this:

6 Front panel audio header Connect one end of the front panel audio cable to the front panel audio header on the DX card, the other end to the chassis-mounted front panel audio I/O module on your motherboard.


There are only two "ends" of the FP audio cable that are readily accessible - the two connectors I've already mentioned, HD and AC'97, which are both essentially on the same end of the cable. That's why I thought it meant one plugged into the motherboard and one into the card - I hadn't even noticed that they were marked differently yet. The only other "end" of the cable is the one connected up inside the FP itself, and it seemed like that ought to stay where it was if the FP jacks were going to be connected up at all, but as I said I'm still in learning mode when it comes to this stuff.

Since I can't look at the motherboard manual right now I can't tell if it means a different pinout on the board entirely - maybe the board is supposed to stay connected to the FP, and a separate connection could run from the board to the card to let the card control the FP jacks? I can't see any other free connector on the board that would take the same type of connector or is marked as FP Audio. There are no other cables coming from the FP that have that kind of 9 pin connector and I can tell from where most of them are plugged into the board that they're for the power switch, LEDs, etc.

Anyway - I'll just park the speaker control thingie in a convenient place and use headphones from that.

The only options I have for Sound Playback in Control Panel are the sound card and "ATI HD Audio rear output" which has got to be the onboard audio from the motherboard, which I disabled when I installed the card per the card's manual. I will reboot though and go into Setup and have a looksee. Maybe there's something there I should've changed and didn't.

The mic I'm not worried about, that can stay plugged into the dedicated jack on the card's rear panel. I haven't tested it yet but I think it should work fine from there. I don't really use the mic very much so it's no biggie unless if I ever get around to installing the voice recognition mod so I can scream commands at the crew and it doesn't work, I'll have to mess with it then.

Thanks again for taking time to help me puzzle this out. Just wait til I get tired of this system! The next time, I *swear* I'm gonna build one entirely from scratch. Won't that be fun? I'm guessing it will go something like this:

Also in XP Control Panel I have an Icon called Audio Console (Creative software), here I can also select the output device and under the tab Headphone Detection you can select Headphone settings and Automatically mute speakers.

Is that something that got added to Control Panel when you installed the sound card? I don't have it but the Xonar DX Audio Center shows up there, that came with my sound card install. There may be something I can do from there - I've only played with it a little and haven't even begun to look at the documentation on it.

Yes this was installed with the card, you should have similar settings here!
Not familiar with your card, did you check to see if there is a jumper on the card to select between front and rear panel, just a thought.
